^^Exactly!  Next to the auto coater and robotic infeed/outfeed drying cabinet.  ;)

What about not having film too?  I bet most decent films block more UV than decent glass...

So why is that M&R not just one unit- CTS followed by LED scan?  That would be slick. 

That's what I thought we were going to see with their unit, but I was just guessing.

And the imagesetter clear film is "supposed" to only block 9% of the UV light and laser paper/vellum blocks 45%.  So perhaps the lack of glass is a bigger time saver than no film.  I would have thought the waterproof inkjet film would block more UV than the glass on our expo unit but I guess I'm wrong.

Somebody actually posted a value for how much each mm of float glass blocks what % of UV on the older message boards.  I used it when going to thicker glass to adjust expo times and it worked!

We use CTS. Surely they have developed a unit for conventional film exposures.

Surely...???  <insert cricket noise>. Anyone? Anyone?  Bueler? Fry?

from what I can tell, there is quite a bit more going on, but they probably have to wait for the official release date. . . Give ti few more days.

And the next post will have the link to the led unit that can hold a 25x36 screen with a film positive taped to it right?  Help a brotha out!!!  :-)

Vacuum, we don't need no stinking vacuum. Back in the day,1998... this guy I know... ::) had no exposure unit. He would lightly spray tack films and affix them to back of the screen, step out the back door of the shop and in one minute would have an exposed screen. Ahh, the good old days.

Don't recall the name, but remember that he was an Aussie, a regular at TSPMB, used to boast of using "turps" to adhere films with no glass or vacuum.

We used to print shirts for the SF MOMA and other museum shops with wood frame screens exposed in the sun. 4 color reproductions of Frida Kahlo, etc.

3M artist adhesive spray. One light coat on the film, stick it to the screen. Bring the screen out on a black fabric covered board. Angle the screen to the sun and lift the cover to expose, then get it inside.

I think the shop manager had some technique for measuring the exposure times by using a camera light meter. I never got the details, I'd just expose at the times she'd tell me on a given day. Worked great.

Films were a fricken MESS though.
